The key word here is 'dissatisfaction.' Also note how Kevin says repeatedly 'don't like'MG: I know this has been asked a million times, but it's just not clear to me. Why should we value absolute truth?
KS: You would only value it if you were dissatisfied with anything less.
And you would be dissatisfied with anything less if you didn't like being proven wrong, or if you didn't like making a fool of yourself, or if you didn't like experiencing avoidable suffering.
Later Kevin responds to Matt:
Notice how Kevin says 'feels good'MG: Being right doesn't put food on the table.
KS: But it feels good. And while it might not put much food on the table right now, in the long term you can reap a harvest
Reminds me of a lecture by the great Charles Sanders Pierce:
The rationalists who are convinced that feelings interfere with the most adaptive choices have the matter completely backwards. A reliance on logic alone, without the capacity to feel the anticipatory states of joy, guilt, sadness, or anxiety that might follow a particular judgment, would lead most people to do many, many more foolish things. Wise commentators on human nature have nominated emotion, not logic, as the basis for human civility and prudent selection of alternatives.Men, many times fancy that they act from reason when in point of fact, the reasons they attribute to themselves are nothing but excuses which unconscious instinct invents to satisfy the teasing whys of the ego. The extent of this self delusion is such as to render philosophical rationalism a farce......Reason then appeals to sentiment in the last resort.......reason, for all the frills it customarily wears in vital crises, comes down upon its marrow bones to beg the help of instinct.
